CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation application of U.S. patent application Ser. No. 14/406,847 filed on Dec. 10, 2014 which is a National Stage Entry of PCT/JP2013/066026, filed Jun. 11, 2013, and claims the benefit of priority from prior Japanese Patent Application JP 2012-141489, filed Jun. 22, 2012, the entire content of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a detection device, a detection method, and a program, and in particular, relates to a detection device, a detection method, and a program for improving operability of a user operation accompanied by contact or pressure, for instance.

BACKGROUND ART

Conventionally, for instance, in a remote controller of a television receiver, a channel and a volume (sound volume) of the television receiver are controlled in response to detection of depression of a channel button and a volume button or the like.

However, in recent years, by introduction of a television receiver capable of displaying a web browser or the like in addition to broadcast programs, a remote controller capable of detecting a user operation accompanied by contact or pressure by a finger of a user or the like to an operation surface has been introduced.

This remote controller can output different command according to different user operations to the same operation surface (for instance, see Patent Literature 1).

That is, for instance, on the operation surface, a pointer operation area to be operated when moving a pointer on a web browser displayed in a television received image and a volume button area to be operated when changing the sound volume of the television receiver are overlapped and arranged.

Therefore, for instance, a user can move the pointer by performing a contact moving operation of moving a finger of the user or the like in a contact state on the pointer operation area within the operation surface.

Also, for instance, the user can make a decision to select a link destination of a uniform resource locator (URL) or the like indicated by the pointer by performing a pressing operation of pressing the pointer operation area within the operation surface. Thus, the user can change display of the web browser to the display of the selected link destination.

Further, for instance, the user can change the sound volume of the television receiver by performing a pressing operation of pressing the volume button area within the operation surface.

SUMMARY OF INVENTION Technical Problem

Now, on the operation surface, the pointer operation area and the volume button area are overlapped and arranged as described above.

-   Therefore, for instance, when the user performs the pressing     operation on an overlap area where the pointer operation area and     the volume button area are overlapped and arranged, the sound volume     of the television receiver may be changed against an intention of     the user.

That is, for instance, sometimes the sound volume of the television receiver is changed even though the user performs the pressing operation of pressing the overlap area with the intention of making a decision to select the link destination of the URL or the like indicated by the pointer, and operability of a user operation to the operation surface is poor.

The present disclosure is implemented in consideration of such circumstances and is to improve the operability of the user operation accompanied by contact and pressure.

DESCRIPTION OF EMBODIMENTS

Hereinafter, embodiments in the present disclosure (called embodiments, hereinafter) will be described. Descriptions will be given in the following order.

1. First embodiment (one example of the time of selecting a user operation area that is a target of a user operation, on the basis of a position with which a finger of a user or the like is brought into contact first)

2. Second embodiment (one example of the time of fixing coordinates of a pointer or the like for some time when a pressing operation by the user is performed)

3. Modification

1. First Embodiment [Appearance Example of Remote Controller 21]

FIG. 1 illustrates an appearance example of a remote controller 21. On a surface of the remote controller 21, together with operation buttons 41, an operation surface 42 a of a touch pad 42 forming a part of the remote controller 21 is provided.

Therefore, a user can perform an operation for turning on a power source of a television receiver 22 or the like using the operation buttons 41 and the operation surface 42 a. The touch pad 42 will be described in detail with reference to FIG. 2.

The operation buttons 41 are constituted of a drag button 41 a or the like in addition to a power button, a reproduction button, a stop button and the like, and operated by the user.

The drag button 41 a is a function key capable of allocating another function to a button having a predetermined function.

That is, for instance, when the user depresses the power button having a function of turning on or off the power source of the television receiver 21 in the state of depressing the drag button 41 a, the power button is to function as another button like the reproduction button or the like for instance.

Also, the user can perform a first drag operation of moving his/her own finger on the operation surface 42 a in the state of pressing the operation surface 42 a with his/her own finger or the like.

In addition, for instance, the user can perform a second drag operation of moving his/her own finger on the operation surface 42 a in the state of depressing the drag button 41 a.

The first drag operation and the second drag operation are both performed in the case of moving an operation target displayed on a display screen of the television receiver 22 or in the case of selecting a prescribed area on the display screen of the television receiver 22 or the like.

In the case of performing the first drag operation, since only the operation surface 42 a should be operated, the user can perform the first drag operation with one hand without using both hands, for instance.

Also, in the case that the user performs the second drag operation using the drag button 41 a, even when the finger or the like is released from the operation surface 42 a, the situation of canceling the second drag operation can be prevented as long as it is the state of depressing the drag button 41 a.

Therefore, when the finger or the like is brought into contact with the operation surface 42 a again, the user can continue the second drag operation.

-   The operation surface 42 a is provided with, as user operation areas     to be the target of the user operation indicating an operation to be     performed by the user, a pointer operation area A, an edge scroll     area B₁, an edge scroll area B₂, an FR button area C₁, and an FF     button area C₂.

Here, as kinds (operation contents) of the user operation, there exists, in addition to the above-described drag operation, a contact moving operation, a pressing operation and the like.

The contact moving operation is an operation of moving the finger of the user or the like in a direction in which the user wants to move a pointer or the like as an operation target, for instance, in the state of bringing his/her own finger or the like into contact with the operation surface 42 a. The pointer is displayed on the display screen of the television receiver 22.

Also, the pressing operation is an operation that the user presses a position on the operation surface 42 a using his/her own finger or the like.

As the pressing operation, for instance, there exist two kinds that are a click operation of pressing the position on the operation surface 42 a while the finger of the user or the like is kept in contact with the operation surface 42 a, and a tap operation of pressing the position on the operation surface 42 a as if tapping (lightly hitting) it in the state that the finger of the user or the like is not in contact with the operation surface 42 a.

The pointer operation area A is provided on the entire surface of the operation surface 42 a as illustrated in FIG. 1, and is the target of the contact moving operation and the pressing operation.

That is, for instance, the pointer operation area A is the target of the contact moving operation when the pointer or the like displayed on the display screen of the television receiver 22 is the operation target and the pointer or the like as the operation target is to be moved.

Also, for instance, the pointer operation area A is the target of the pressing operation when the link destination of a uniform resource locator (URL) or the like existing at the position indicated by the pointer or the like is the operation target and the link destination as the operation target is to be specified.

In the pointer operation area A, in a vertically long partial area that is present on the right side in the figure and extends in a vertical direction (longitudinal direction) in the figure, the edge scroll area B₁ is overlapped and provided.

The edge scroll area B₁ is the target of the contact moving operation when a scroll bar for scrolling the display screen of the television receiver 22 in the vertical direction is the operation target and the scroll bar is to be moved.

Also, in the edge scroll area B₁, a lower end portion of the edge scroll area B₁ is the target of the pressing operation when content displayed on the display screen of the television receiver 22 is the operation target and the content as the operation target are to be fast-forwarded.

The lower end portion of the edge scroll area B₁ indicates the same part as the part provided with the FF button area C₂.

Further, in the pointer operation area A, in a horizontally long partial area that is present on the lower side in the figure and extends in a horizontal direction (lateral direction) in the figure, the edge scroll area B₂ is overlapped and provided.

The edge scroll area B₂ is the target of the contact moving operation when a scroll bar for scrolling the display screen of the television receiver 22 in the horizontal direction is the operation target and the scroll bar is to be moved.

Also, in the edge scroll area B₂, a lower left portion of the edge scroll area B₂ is the target of the pressing operation when content displayed on the display screen of the television receiver 22 is the operation target and the content as the operation target are to be rewound.

A left end portion of the edge scroll area B₂ indicates the same part as the part provided with the FR button area C₁.

Further, in the edge scroll area B₂, a lower right portion of the edge scroll area B₂ is the target of the pressing operation when content displayed on the display screen of the television receiver 22 is the operation target and the content as the operation target are to be fast-forwarded.

The lower right portion of the edge scroll area B₂ indicates the same part as the part provided with the FF button area C₂.

The FR button area C₁ is the target of the pressing operation when the content displayed on the display screen of the television receiver 22 is the operation target and the content as the operation target are to be rewound.

The FF button area C₂ is the target of the pressing operation when the content displayed on the display screen of the television receiver 22 is the operation target and the content as the operation target are to be fast-forwarded.

Also, the FR button area C₁ and the FF button area C₂ use the content as the operation target, and form a button area C that is the target of the pressing operation when the content is rewound and fast-forwarded as the operation target.

That is, on the operation surface 42 a, as the user operation areas for which the operation target is different though the operation content of the user operation is the same, the pointer operation area A and the edge scroll areas B₁ and B₂ are overlapped and arranged.

Also, on the operation surface 42 a, as the user operation areas for which the operation content and the operation target are both different, the pointer operation area A and the button area C are overlapped and arranged, and also the edge scroll areas B₁ and B₂ and the button area C are overlapped and arranged.

As described above, in the pointer area A, for instance, the pointer and the link destination and the like are the operation target, and the contact moving operation and the pressing operation are adopted as the operation content of the user operation.

Also, in the edge scroll areas B₁ and B₂, for instance, the scroll bar and the content are the operation target, and the contact moving operation and the pressing operation are adopted as the operation content of the user operation.

Further, in the button area C, for instance, the content is the operation target, and the pressing operation is adopted as the operation content of the user operation.

Hereinafter, the pointer operation area A, the edge scroll areas B₁ and B₂, and the button area C are also called user operation areas A, B₁, B₂ and C, respectively.

The remote controller 21 calculates a start position on the operation surface 42 a on the basis of a detection result of at least one of contact of a user finger with or the like or pressure of a user finger or the like on the operation surface 42 a, for instance. Also, the contact with or the pressure on the operation surface 42 a are detected by the touch pad 42.

Also, the start position indicates a position on the operation surface 42 a when the contact with the operation surface 42 a is started.

That is, for instance, the remote controller 21 calculates a centroid of a contact surface where the finger of the user or the like and the operation surface 42 a are brought into contact or the like as the start position, on the basis of the detection result of the contact of the user finger or the like with the operation surface 42 a.

Also, for instance, the remote controller 21 can also calculate a position where a pressure by the finger of the user or the like is the largest as the start position, on the basis of the detection result of the pressure of the user finger or the like on the operation surface 42 a.

Further, for instance, the remote controller 21 may calculate the start position on the basis of the detection result of the contact and the pressure by the user finger or the like. In the first embodiment, it is assumed that the remote controller 21 calculates the start position on the basis of the detection result of the contact and the pressure by the user finger or the like.

Also, the remote controller 21 selects a target user operation area indicating the user operation area that is the target of the user operation from the plurality of user operation areas A, B₁, B₂ and C on the operation surface 42 a, on the basis of the calculated start position on the operation surface 42 a.

Further, the remote controller 21 detects the operation content of the user operation and the operation target of the user operation, on the basis of the detection result of the contact with and the pressure on the target user operation area on the operation surface 42 a.

Then, the remote controller 21 controls the television receiver 22, on the basis of the detection result.

That is, for instance, the remote controller 21 generates IR signals for controlling the television receiver 22, and emits the IR signals to the television receiver 22 as radio signals, on the basis of the detection result of the operation content of the user operation and the operation target of the user operation.

The television receiver 22 receives the IR signals from the remote controller 21, and performs processing of moving the pointer or the like that is the operation target according to the operation content of the user operation, for instance, on the basis of the received IR signals.

[Detail of Touch Pad 42]

Next, FIG. 2 illustrates a detailed configuration example of the touch pad 42.

The touch pad 42 forms a part of the remote controller 21, and is constituted of the operation surface 42 a, a switch 42 b, and elastic bodies 42 c ₁ and 42 c ₂.

The operation surface 42 a includes a capacitance sensor or the like that detects a change in electrostatic capacitance of the operation surface 42 a, and detects the contact of the finger of the user or the like with the operation surface 42 a on the basis of the change in the electrostatic capacitance of the operation surface 42 a.

The switch 42 b is provided on a back side of the operation surface 42 a (the back side of the surface where the contact and pressure of the finger of the user or the like are performed), and is turned from an off state to an on state by being pressurized by the operation surface 42 a. That is, the switch 42 b detects the pressure of the finger of the user or the like on the operation surface 42 a in response to the fact that it is turned to the on state.

Also, the detection result on the operation surface 42 a and the detection result in the switch 42 b are outputted to a processing unit 43 (to be described later in FIG. 3) that detects the operation content and the operation target of the user operation.

The elastic bodies 42 c ₁ and 42 c ₂ are the elastic bodies of a spring or the like, and support the operation surface 42 a so as to be in parallel with a bottom surface of the remote controller 21 when the pressure on the operation surface 42 a is not being performed.

Now, the operation surface 42 a can also detect the pressure (pressurization) of the finger of the user or the like on the operation surface 42 a, on the basis of the change in the electrostatic capacitance. Therefore, when the pressure on the operation surface 42 a is also detected on the operation surface 42 a, the switch 42 b can be omitted.

[Configuration Example of Remote Controller 21]

Next, FIG. 3 illustrates a configuration example of the remote controller 21. The remote controller 21 is constituted of the operation buttons 41 including the drag button 41 a, the touch pad 42 mainly including the operation surface 42 a and the switch 42 b, the processing unit 43, an area selection unit 44, a time measurement unit 45, and an IR transmission unit 46.

The operation buttons 41 are, as illustrated in FIG. 1, composed of the drag button 41 a or the like in addition to the power button, the reproduction button, the stop button and the like, and operated by the user. The operation buttons 41 supply operation signals corresponding to the operation by the user to the processing unit 43 according to the fact that the operation buttons are operated by the user.

The touch pad 42 is, as illustrated in FIG. 2, constituted mainly of the operation surface 42 a and the switch 42 b. The operation surface 42 a detects the contact with the operation surface 42 b on the basis of the change in the electrostatic capacitance of the operation surface 42 a, and supplies the detection result to the processing unit 43. The switch 42 b detects the pressure on the operation surface 42 a, and supplies the detection result to the processing unit 43.

The processing unit 43 calculates the position when the contact of the finger of the user or the like with the operation surface 42 a is started, as the start position on the operation surface 42 a, on the basis of the detection results from the operation surface 42 a and the switch 42 b, and supplies it to the area selection unit 44.

Also, the processing unit 43 detects the operation content of the user operation and the operation target of the user operation, on the basis of the detection results supplied from the operation surface 42 a and the switch 42 b and (information indicating) the target user operation area from the area selection unit 44, and supplies the detection result to the IR transmission unit 46.

Further, when a series of user operations to the operation surface 42 a are ended, the processing unit 43 determines whether or not the last user operation is a moving contact operation of moving the pointer or the like, on the basis of the detection results from the operation surface 42 a and the switch 42 b.

Then, when it is determined that the last user operation is the moving contact operation of moving the pointer or the like on the basis of the detection results from the operation surface 42 a and the switch 42 b, the processing unit 43 controls the time measurement unit 45, and makes it start measuring required time to be described later.

Also, when a new series of user operations to the operation surface 42 a are started, the processing unit 43 controls the time measurement unit 45, and makes it end measurement of the required time.

Thus, the time measurement unit 45 measures the required time needed after the finger of the user or the like is released from the operation surface 42 a until it is brought into contact according to the control from the processing unit 43, and supplies it to the area selection unit 44.

Further, the processing unit 43 detects the operation content and the operation target of the user operation to the operation buttons 41, on the basis of the operation signals from the operation buttons 41, and supplies the detection result to the IR transmission unit 46.

The area selection unit 44 selects the target user operation area indicating the user operation area to be the target of the user operation from the plurality of user operation areas A, B₁, B₂ and C on the operation surface 42 a, on the basis of the start position from the processing unit 43, and supplies it to the processing unit 43.

Also, when the required time is supplied from the time measurement unit 45, the area selection unit 44 selects the target user operation area from the plurality of user operation areas A, B₁, B₂ and C, on the basis of the required time from the time measurement unit 45 as well in addition to the start position from the processing unit 43.

A first selection method with which the area selection unit 44 selects the target user operation area on the basis of the start position from the processing unit 43 will be described in detail with reference to FIGS. 4A, 4B, 5, 6A, and 6B. Also, a second selection method with which the area selection unit 44 selects the target user operation area on the basis of the required time from the time measurement unit 45 as well in addition to the start position from the processing unit 43 will be described in detail with reference to FIG. 7.

As described above, the time measurement unit 45 measures the required time needed after the finger of the user or the like is released from the operation surface 42 a until it is brought into contact according to the control from the processing unit 43, and supplies the required time obtained by the measurement to the area selection unit 44.

The IR transmission unit 46 generates the IR signals for controlling the television receiver 22 on the basis of the detection result from the processing unit 43, and transmits the IR signals to the television receiver 22 as the radio signals. That is, for instance, the IR transmission unit 46 decides the operation corresponding to the target user operation area on the basis of the detection result from the processing unit 43, and generates and transmits the IR signals for making the decided operation be performed.

Next, FIGS. 4A and 4B illustrate one example of the time when the display screen of the television receiver 22 is scrolled against an intention of the user since the contact moving operation is performed after the click operation.

FIG. 4A illustrates one example of the time when the click operation is performed at a click position 61 inside the FR button area C₁, the contact moving operation is performed from the click position 61 to a click position 62 inside the FF button area C₂, and a new click operation is performed at the click position 62 as a series of user operations.

It is assumed that the user is performing the series of user operations illustrated in FIG. 4A with the intention of rewinding and fast-forwarding the content displayed at the television receiver 22 in order to reproduce the content from a desired reproducing position.

Also, it is assumed that the click position 61 is the start position on the operation surface 42 a.

FIG. 4B illustrates one example of the time when the display screen displaying content 64 is scrolled against the intention of the user since a scroll bar 63 is moved in a right direction in the figure by the series of user operations illustrated in FIG. 4A on the display screen of the television receiver 22.

For instance, when the user performs the series of user operation as illustrated in FIG. 4A, on the display screen of the television receiver 22, the content 64 is rewound by the click operation at the click position 61 as illustrated in FIG. 4B.

Then, on the display screen of the television receiver 22, the scroll bar 61 may be moved against the intention of the user and the display screen may be scrolled by the contact moving operation performed inside the edge scroll area B₂.

Therefore, the area selection unit 44 of the remote controller 21 selects the button area C as the target user operation area C from the plurality of user operation areas A, B₁, B₂ and C, on the basis of the click position 61 as the start position on the operation surface 42 a.

Then, the processing unit 43 detects only the user operation targeting the target user operation area C selected in the area selection unit 44 until the series of user operations to the operation surface 42 a are ended.

Thus, until the series of user operations illustrated in FIG. 4A are ended, in the processing unit 43, only the pressing operation targeting the button area C (the FR button area C₁ and the FF button area C₂) is detected.

Also, the processing unit 43 identifies the end of the series of user operations illustrated in FIG. 4A when it is determined that the finger of the user or the like is released from the operation surface 42 a, for instance.

For instance, the processing unit 43 may identify the end of the series of user operations illustrated in FIG. 4A when it is determined that the finger of the user is in contact for the predetermined time or longer at an arbitrary position on the operation surface 42 a.

In this case, the processing unit 43 calculates a new start position assuming that the contact of the finger of the user or the like is newly started when it is determined that the finger of the user is in contact for the predetermined time or longer at the arbitrary position on the operation surface 42 a after identifying the end of the series of user operations for instance.

Also, the present technology is not limited to the remote controller 21 as illustrated in FIG. 1, and is also applicable to a remote controller 21′ as illustrated in FIG. 5 for instance.

In the remote controller 21′ in FIG. 5, the entire surface of the remote controller 21′ is an operation surface 42 a′.

On the operation surface 42 a′, as illustrated on a lower side in FIG. 5, for instance, a volume operation area B₂′ to be operated when changing the sound volume (volume), a power button area that functions as a power button, a pointer operation area, a menu button area that functions as a menu button, and a cross key area that functions as cross keys are provided.

In the volume operation area B₂′, the sound volume of the content is the operation target, and the contact moving operation is adopted as the operation content of the user operation.

Therefore, for instance, when the user performs the contact moving operation of moving the finger of the user or the like from a left direction to a right direction in the figure on the volume operation area B₂′, the sound volume of the content displayed on the display screen is turned to a larger sound volume.

Also, for instance, when the user performs the contact moving operation of moving the finger of the user or the like from the right direction to the left direction in the figure on the volume operation area B₂′, the sound volume of the content displayed on the display screen is turned to a smaller sound volume.

Also, the longer a moving distance of the finger of the user or the like is or the faster the movement when moving the finger of the user or the like is, the greater the sound volume is to change.

In the volume operation area B₂′, as illustrated on an upper side in FIG. 5, a volume down area C₁′ is overlapped and provided in a rectangular area present on the left side in the figure, and a volume up area C₂′ is overlapped and provided in a rectangular area present on the right side in the figure.

The volume down area C₁′ and the volume up area C₂′ configure a volume area C′ where the sound volume of the content is the operation target and the pressing operation is adopted as the operation content of the user operation.

For instance, when the user performs the pressing operation on the volume down area C₁′, the sound volume of the content displayed on the display screen is turned to the sound volume smaller by a predetermined change amount.

Also, when the user performs the pressing operation on the volume up area C₂′, the sound volume of the content displayed on the display screen is turned to the sound volume larger by a predetermined change amount.

In FIG. 5, on the operation surface 42 a′, as the user operation areas for which the operation target is the same though the operation content of the user operation is different, the volume operation area B₂′ and the volume area C′ (the volume down area C₁′ and the volume up area C₂′) are overlapped and arranged.

For instance, when the user performs the series of user operation for adjusting the sound volume by performing the click operation to the volume down area C₁′ and the volume up area C₂′, a phenomenon similar to the case described in FIGS. 4A and 4B may occur against the intention of the user.

Also, the volume operation area B₂′, the volume down area C₁′, and the volume up area C₂′ correspond to the edge scroll area B₂, the FR button area C₁, and the FF button area C₂ illustrated in FIG. 4A, respectively.

That is, for instance, the user performs the click operation at a click position 61′ on the volume down area C₁′, and then moves the finger from the click position 61′ to a click position 62′ in order to newly perform the click operation at the click position 62′ on the volume down area C₂′.

In this case, the contact moving operation from the click position 61′ to the click position 62′ is to be performed in the volume operation area B₂′, and the sound volume may increase by a change amount according to the speed of the finger of the user or the like against the intention of the user.

Therefore, similarly in the remote controller 21′, the volume area C′ is selected as the target user operation area C′ from the plurality of user operation areas B₂′ and C′, on the basis of the click position 61′ as the start position on the operation surface 42 a′.

Then, the remote controller 21′ detects only the user operation targeting the target user operation area C until the series of user operations to the operation surface 42 a′ are ended.

Thus, until the series of user operations for adjusting the sound volume are ended, in the remote controller 21′, only the pressing operation targeting the volume area C′ (the volume down area C₁′ and the volume up area C₂′) is detected.

That is, as described with reference to FIG. 1 to FIG. 5, the present technology is applicable to the following remote controller.

That is, the present technology is applicable to the remote controller including the operation surface where the user operation areas which are the target of the user operation and detected according to the user operation and in which at least one of the operation content of the user operation and the operation target of the user operation is different are overlapped and arranged.

Specifically, for instance, the present technology is applicable to the remote controller 21 including the operation surface 42 a where the user operation areas for which the operation content of the user operation is the same and the operation target is different are overlapped and arranged.

Also, for instance, the present technology is applicable to the remote controller 21 including the operation surface 42 a where the user operation areas for which the operation content and the operation target of the user operation are both different are overlapped and arranged.

Further, the present technology is applicable to the remote controller 21′ including the operation surface 42 a′ where the volume operation area B₂′ and the volume area C′ are overlapped and arranged as the user operation areas for which the operation content of the user operation is different and the operation target is the same.

Next, FIGS. 6A and 6B illustrate one example of the time when the content is fast-forwarded against the intention of the user since the click operation of making a decision is performed at a position indicated by the pointer after the contact moving operation of moving the pointer.

FIG. 6A illustrates one example of the time when the contact moving operation of the finger of the user is performed from a start position 81 to a click position 82 in the state that the finger of the user is in contact with the operation surface 42 a, and the click operation is performed at the click position 82 after the contact moving operation as the series of user operations.

The start position 81 is assumed to be a position on the pointer operation area A where any of the edge scroll areas B₁ and B₂, the FR button area C₁, and the FF button area C₁ is not overlapped.

FIG. 6B illustrates one example of the time when content 84 is fast-forwarded against the intention of the user by the series of user operations illustrated in FIG. 6A.

For instance, when the user performs the series of user operations as illustrated in FIG. 6A, on the display screen of the television receiver 22, a pointer 83 is moved in a downward direction as illustrated in FIG. 6B by the contact moving operation of moving from the start position 81 to the click position 82.

Then, on the display screen of the television receiver 22, the content 84 may be fast-forwarded against the intention of the user by the click operation performed at the click position 82 inside the FF button area C₂.

That is, for instance, the content 84 may be fast-forwarded even though the user performs the click operation with the intention of a decision to select the link destination of the URL or the like indicated by the pointer 83.

Therefore, the area selection unit 44 of the remote controller 21 selects the pointer operation area A as the target user operation area A from the plurality of user operation areas A, B₁, B₂ and C, on the basis of the start position 81 on the operation surface 42 a.

Then, the processing unit 43 detects only the user operation targeting the target user operation area A selected in the area selection unit 44 until the series of user operations to the operation surface 42 a are ended.

Thus, since the processing unit 43 detects the click operation at the click position 82 as the click operation intended to make a decision to select the link destination of the URL or the like indicated by the pointer 83, it is possible to prevent the situation that the content 84 is fast-forwarded against the intention of the user.

While the example of the time when the click operation is performed at the click position 82 has been described in FIG. 6A, for instance, it is possible that the user releases the contact of the finger of the user once at the click position 82 and then performs the tap operation at the click position 82.

In this case, when the tap operation is performed immediately after the contact of the finger of the user is released, the tap operation is intended to make a decision at the position indicated by the pointer 83. Also, when the tap operation is performed after the lapse of a certain length of time after the contact of the finger of the user is released, the tap operation is intended to fast-forward the content 84.

Next, FIG. 7 illustrates one example of the time when determining whether the tap operation performed at the click position 82 is the tap operation intended to make a decision at the position indicated by the pointer 83 or the tap operation intended to fast-forward the content 84.

In FIG. 7, a horizontal axis indicates the time and a vertical axis indicates a position y in a Y axis direction on the operation surface 42 a. Here, the Y axis direction is the direction where the edge scroll area B₁ extends vertically long. In FIG. 7, in order to simplify descriptions, a position x in an X axis direction vertical to a Y axis is omitted. Also, in FIG. 7, positions y₁, y₂, y₃ and y₄ indicate the start position when the contact with the operation surface 42 a is started, respectively.

Further, at the positions y₁, y₂, y₃ and y₄, the positions y₁ and y₂ indicate the positions on the pointer operation area A where any of the edge scroll areas B₁ and B₂, the FR button area C₁, and the FF button area C₂ is overlapped, respectively. Also, the positions y₃ and y₄ indicate the positions on the FF button area C₂.

Further, positions y₁′, y₂′, y₃′ and y₄′ indicate the positions on the FF button area C₂ and are the positions when the contact with the operation surface 42 a is released, respectively.

As illustrated on a left side in FIG. 7, when the contact moving operation is performed from the position y₁ to the position y₁′ and the click operation is performed at the position y₁′, the area selection unit 44 selects the pointer operation area A as the target user operation area A on the basis of the start position y₁ as the start position 81.

In this case, the click operation at the position y₁′ is detected by the processing unit 43 as the click operation intended to make a decision at the position indicated by the pointer 83.

Also, as illustrated at the center in FIG. 7, the area selection unit 44 selects the target user operation area on the basis of whether or not required time T1 after the contact moving operation is performed from the position y₂ to the position y₂′ and the contact of the finger of the user or the like is released at the position y₂′ until the tap operation is performed is shorter than predetermined fixed time Tw.

Here, the required time T1 is the time needed after the contact of the finger of the user or the like is released at the position y₂′ until the finger of the user or the like is brought into contact at the position y₃ by the tap operation.

At the center in FIG. 7, since the required time T1 is shorter than the fixed time Tw, the area selection unit 44 selects the pointer operation area A as the target user operation area A.

In this case, the tap operation at the position y₃ is detected by the processing unit 43 as the tap operation intended to make a decision at the position indicated by the pointer 83, and the tap operation intended to fast-forward the content 84 is not detected.

Further, as illustrated on the right side in FIG. 7, the area selection unit 44 selects the target user operation area on the basis of whether or not required time T2 after the contact of the finger of the user or the like is released at the position y₃′ until the tap operation is performed is shorter than predetermined fixed time Tw.

Here, the required time T2 is the time needed after the contact of the finger of the user or the like is released at the position y₃′ until the finger of the user or the like is brought into contact at the position y₄ by the tap operation.

On the right side in FIG. 7, since the required time T2 is not shorter than the fixed time Tw, the area selection unit 44 selects the button area C (the FR button area C₁ and the FF button area C₂) as the target user operation area C.

In this case, the tap operation at the position y₄ is detected by the processing unit 43 as the tap operation intended to fast-forward the content 84.

[Operation Description of Remote Controller 21 in FIG. 3]

Next, with reference to a flowchart in FIG. 8, operation detection processing performed by the remote controller 21 in FIG. 3 will be described.

In step S21, the touch pad 42 detects the contact with and the pressure on the operation surface 42 a, and supplies the detection result to the processing unit 43.

That is, the operation surface 42 a of the touch pad 42 detects the contact of the finger of the user or the like with the operation surface 42 a, on the basis of the change in the electrostatic capacitance obtained from a built-in capacitance sensor or the like, and supplies the detection result to the processing unit 43.

The switch 42 b of the touch pad 42 detects the pressure on the operation surface 42 a, and supplies the detection result to the processing unit 43.

In step S22, the processing unit 43 determines whether or not the finger of the user or the like is brought into contact with the operation surface 42 a on the basis of the detection results from the operation surface 42 a and the switch 42 b, and repeats the processing in step S21 and step S22 until it is determined that the finger of the user or the like is brought into contact with the operation surface 42 a.

Then, in step S22, when it is determined that the finger of the user or the like is brought into contact with the operation surface 42 a on the basis of the detection results from the operation surface 42 a and the switch 42 b, the processing unit 43 advances the processing to step S23.

In step S23, the processing unit 43 calculates the start position on the operation surface 42 a on the basis of the detection results from the operation surface 42 a and the switch 42 b, and supplies it to the area selection unit 44.

In step S24, the area selection unit 44 performs target area selection processing of selecting the target user operation area to be the target of the series of user operations from the plurality of user operation areas A, B₁, B₂ and C on the basis of the start position on the operation surface 42 a from the processing unit 43.

The area selection unit 44 supplies the target user operation area selected by the target area selection processing to the processing unit 43.

Also, the target area selection processing in step S24 will be described in detail with reference to a flowchart in FIG. 9.

In step S25, the processing unit 43 detects the operation content of the user operation to the operation surface 42 a and the operation target of the user operation on the basis of the detection results from the operation surface 42 a and the switch 42 b and the target user operation area from the area selection unit 44, and supplies the detection result to the IR transmission unit 46.

In step S26, the IR transmission unit 46 generates the IR signals for controlling the television receiver 22 on the basis of the detection result from the processing unit 43, and transmits (emits) them to the television receiver 22 as the radio signals.

In step S27, the processing unit 43 determines whether or not the finger of the user or the like in contact with the operation surface 42 a is released from the operation surface 42 a, on the basis of the detection results from the operation surface 42 a and the switch 42 b.

When it is determined that the finger of the user or the like is not released from the operation surface 42 a on the basis of the detection results from the operation surface 42 a and the switch 42 b, the processing unit 43 returns the processing to step S25, and the similar processing is performed thereafter in step S25.

Also, when it is determined that the finger of the user or the like is released from the operation surface 42 a on the basis of the detection results from the operation surface 42 a and the switch 42 b, that is, when it is determined that the series of user operations are ended, the processing unit 43 advances the processing to step S28.

In step S28, the processing unit 43 determines whether or not the last user operation is the contact moving operation targeting the pointer operation area A in response to the determination of the end of the series of user operations.

When it is determined that the last user operation is not the contact moving operation targeting the pointer operation area A, the processing unit 43 skips step S29, and ends the operation detection processing.

Also, in step S28, when it is determined that the last user operation is the contact moving operation targeting the pointer operation area A, the processing unit 43 advances the processing to step S29, and controls the time measurement unit 45.

In step S29, the time measurement unit 45 measures the required time needed after the finger of the user or the like is released from the operation surface 42 a until it is brought into contact with the operation surface 42 a again according to the control from the processing unit 43.

Also, in step S29, the time measurement unit 45 ends the measurement of the required time according to the control from the processing unit 43 and supplies the measured required time to the area selection unit 44, and the operation detection processing is ended. That is, the processing unit 43 makes the time measurement unit 45 measure the required time until it is determined that the finger of the user or the like is brought into contact with the operation surface 42 a in step S22 of new operation detection processing.

[Details of Target Area Selection Processing]

Next, with reference to the flowchart in FIG. 9, details of the target area selection processing in step S24 in FIG. 8 will be described.

-   In step S41, the area selection unit 44 determines whether or not     the start position on the operation surface 42 a from the processing     unit 43 is the position on the user operation area C.

When it is determined that the start position on the operation surface 42 a from the processing unit 43 is not the position on the user operation area C, the area selection unit 44 advances the processing to step S42.

In step S42, the area selection unit 44 determines whether or not the start position on the operation surface 42 a from the processing unit 43 is the position on the user operation areas B₁ or B₂.

Then, when it is determined that the start position on the operation surface 42 a from the processing unit 43 is not the position on the user operation area B₁ or B₂, that is, when it is determined that it is the position on the user operation area A where any of the user operation areas B₁, B₂ and C is not overlapped, the area selection unit 44 advances the processing to step S43.

In step S43, the area selection unit 44 selects the user operation area A as the target user operation area A.

Also, in step S42, when it is determined that the start position on the operation surface 42 a from the processing unit 43 is the position on the user operation area B₁ or B₂, the area selection unit 44 advances the processing to step S44, and selects the user operation area B (one of the user operation areas B₁ and B₂) including the start position.

In step S41, when it is determined that the start position on the operation surface 42 a from the processing unit 43 is the position on the user operation area C, the area selection unit 44 advances the processing to step S45.

In step S45, the area selection unit 44 determines whether or not the last user operation is the contact moving operation targeting the user operation area (pointer operation area) A, on the basis of whether or not the required time is supplied from the time measurement unit 45.

When it is determined that the last user operation is not the contact moving operation targeting the user operation area A, the area selection unit 44 skips step S46, and advances the processing to step S47.

Also, in step S45, when it is determined that the last user operation is the contact moving operation targeting the user operation area A, that is, when the required time is supplied from the time measurement unit 45, the area selection unit 44 advances the processing to step S46.

In step S46, the area selection unit 44 determines whether or not the required time from the time measurement unit 45 is shorter than the predetermined fixed time Tw, and when it is determined that the required time is shorter than the fixed time, advances the processing to step S43, and selects the user operation area A as the target user operation area A.

Also, in step S46, when it is determined that the required time from the time measurement unit 45 is not shorter than the predetermined fixed time Tw, the area selection unit 44 advances the processing to step S47, and selects the user operation area C as the target user operation area C. Thereafter, the processing returns to step S24 in FIG. 8, and the processing thereafter is performed.

As described above, in the operation detection processing, the target user operation area to be the target of the user operation is selected from the plurality of user operation areas on the basis of the start position on the operation surface 42 a, for instance.

Therefore, in the remote controller 21 or the like including the operation surface 42 a where the user operation areas A, B₁, B₂ and C which are detected according to the user operation and in which at least one of the operation content and the operation target of the user operation is different are overlapped and arranged, it is possible to prevent the situation of detecting the operation against the intention of the user.

Thus, in the remote controller 21, it is possible to improve operability to the operation surface 42 a.

Now, when the user performs the pressing operation to the operation surface 42 a, the contact surface on the operation surface 42 a where the finger of the user is brought into contact changes according to the change of a pressure to the operation surface 42 a.

Since coordinates calculated according to the user operation are calculated on the basis of the area of the contact surface of the finger of the user and the operation surface 42 a, for instance, the pointer may be moved against the intention of the user during the pressing operation. Also, the coordinates are calculated as the ones indicating the position of the pointer 83 on the display screen, for instance.

Then, it is desirable to prevent the movement of the pointer 83 against the intention of the user by fixing the coordinates of the pointer 83 or the like regardless of the user operation to the operation surface 42 a during the pressing operation.

2. Second Embodiment [Another Configuration Example of Remote Controller 21]

Next, FIG. 10 illustrates another configuration example of the remote controller 21, which improves the operability more by preventing the movement of the pointer against the intention of the user.

In the remote controller 21 in FIG. 10, parts configured similarly to the remote controller in FIG. 3 are denoted with the same reference signs so that the descriptions are appropriately omitted below.

That is, the remote controller 21 in FIG. 10 is configured similarly to the remote controller 21 in FIG. 3 other than that a processing unit 101 incorporating a timing unit 101 a is provided instead of the processing unit 43 in FIG. 3 and a coordinate holding unit 102 is newly provided.

The processing unit 101 performs the processing similar to the processing unit 43 in FIG. 3. That is, for instance, the processing unit 101 detects the operation content and the operation target of the user operation on the basis of the detection results from the operation surface 42 a and the switch 42 b and the target user operation area from the area selection unit 44.

Also, for instance, when the pointer operation area A is supplied as the target user operation area from the area selection unit 44, the processing unit 101 calculates the coordinates of the pointer 83 on the basis of the detected operation content of the user operation, and supplies them to the IR transmission unit 46.

The IR transmission unit 46 generates the IR signals including the coordinates supplied from the processing unit 101 on the basis of the detection result from the processing unit 101, and transmits them to the television receiver 22.

In the second embodiment, the description is given assuming that the processing unit 101 calculates the coordinates of the pointer 83. However, the IR transmission unit 46 may calculate the coordinates of the pointer 83 on the basis of the operation content of the user operation included in the detection result from the processing unit 101, and may generate the IR signals including the calculated coordinates. Further, for instance, the processing unit 101 supplies the coordinates calculated when the depressing operation by the user which targets the pointer operation area A is performed to the coordinate holding unit 102 to be held.

Now, the operation surface 42 a can also detect the presence/absence of the pressure of the finger of the user or the like on the operation surface 42 a, on the basis of the change in the electrostatic capacitance. Therefore, when the presence/absence of the pressure on the operation surface 42 a is also detected on the operation surface 42 a, the switch 42 b can be omitted.

The processing unit 101 supplies the coordinates already held in the coordinate holding unit 102 from the time when the switch 42 b is turned to the off state to the IR transmission unit 46 as the coordinates of the pointer 83 for instance, together with the detection result of the operation content and the operation target of the user operation.

Then, the processing unit 101 performs the processing of supplying the coordinates already held in the coordinate holding unit 102 to the IR transmission unit 46 as the coordinates of the pointer 83 until the elapsed time after the switch 42 b is turned to the off state exceeds the predetermined coordinate fixation time.

That is, for instance, the processing unit 101 supplies the coordinates already held in the coordinate holding unit 102 to the IR transmission unit 46 as the coordinates of the pointer 83 in response to the identification that the switch 42 b is turned to the on state on the basis of the detection result from the switch 42 b.

Then, the processing unit 101 makes the built-in timing unit 101 a start timing in response to the identification that the switch 42 b is turned to the off state on the basis of the detection result from the switch 42 b.

For instance, the processing unit 101 incorporates the timing unit 101 a, and the timing unit 101 a times the elapsed time after the switch 42 b is turned to the off state.

The processing unit 101 determines whether or not the predetermined coordinate fixation time has elapsed from the time when the switch 42 b is turned to the off state, on the basis of a timing result of the built-in timing unit 101 a.

Then, the processing unit 101 supplies the coordinates already held in the coordinate holding unit 102 to the IR transmission unit 46 until the coordinate fixation time elapses from the time when the switch 42 b is turned to the off state.

It is recognized by an analysis result of analyzing log data or the like of general users or the like that the user hardly performs the contact moving operation of moving the pointer 83 or the like immediately after ending the pressure on the operation surface 42 b.

Therefore, for instance, the coordinate fixation time is defined as the time shorter than the average time immediately after ending the pressure on the operation surface 42 b until performing the contact moving operation of moving the pointer 83 or the like.

The IR transmission unit 46 generates the IR signals including the coordinates supplied from the processing unit 101 similarly on the basis of the detection result from the processing unit 101, and transmits them to the television receiver 22. The coordinates included in the IR signals are used, for instance, as information indicating the position of the pointer 83 or the like on the display screen of the television receiver 22. While the coordinate fixation time is predetermined, otherwise, it may be the different fixation time according to the user for instance.

That is, for instance, before the remote controller 21 in FIG. 10 is used, the processing unit 101 makes the user perform the pressing operation targeting the operation surface 42 a, and determines the coordinate fixation time by the area of the contact surface obtained from the pressing operation, the pressing time during which the switch 42 b is turned to the on state, and the like.

Further, for instance, the processing unit 101 may hold a history of the area of the contact surface, the pressing time and the like obtained by the pressing operation by the user, and may change the coordinate fixation time on the basis of the history.

Also, for instance, the coordinate fixation time may be appropriately determined on the basis of the pressing time during which the switch 42 b is turned to the on state.

The coordinate holding unit 102 holds the coordinates supplied from the processing unit 101.

Next, FIGS. 11A, 11B, 11C, 11D, and 11E illustrate the change of the coordinates during the pressing operation by the user or the like.

FIG. 11A illustrates one example of a situation that the centroid of the contact surface of the operation surface 42 a and the finger of the user or the like is changed (displaced) when the pressing operation by the user is performed.

FIG. 11B illustrates one example of the time when the switch 42 b is turned to the on state or the off state according to the pressing operation by the user.

FIG. 11C illustrates one example of the situation of the change of the coordinates when the calculated coordinates are outputted as they are without fixing the coordinates.

FIG. 11D illustrates one example of the situation of the change of the coordinates when the coordinates are fixed (locked) only for the pressing time indicating the time during which the switch 42 b is turned to the on state.

FIG. 11E illustrates one example of the situation of the change of the coordinates when the coordinates are fixed for the coordinate fixation time longer than the pressing time after the time when the switch 42 b is turned to the on state, further.

As illustrated in FIG. 11A, it is recognized by experiments conducted by the present inventor that the centroid of the contact surface with the operation surface 42 a is changed by the pressing operation by the user.

When using the coordinates as illustrated in FIG. 11C, the pointer 83 may be moved up and down against the intention of the user in response to the fact that the pressing operation for making a decision at the position of the pointer 83 is performed.

Therefore, as illustrated in FIG. 11D, it is desirable to suppress the situation that the pointer 83 is moved against the intention of the user by fixing the coordinates of the pointer 83 for the pressing time during which the switch 42 b is turned to the on state. However, when fixing the coordinates of the pointer 83 for the pressing time, the pointer 83 may be moved in an upward direction as illustrated in FIG. 11D after the switch 42 b is turned to the off state.

Therefore, in the present disclosure, as illustrated in FIG. 11E, the coordinates of the pointer 83 or the like are fixed (locked) for some time even after the switch 42 b is turned to the off state, and the situation that the pointer 83 is moved against the intention of the user is prevented.

Also, though the coordinates of the time when the switch 42 b is turned to the on state are different from the coordinates immediately before the switch 42 b is turned to the on state, it is recognized by the experiments conducted by the present inventor that the different is small.

Therefore, in the remote controller 21 in FIG. 10, the coordinates of the time when the switch 42 b is turned to the on state are fixed as the coordinates of the pointer 83 or the like.

Also, in the remote controller 21 in FIG. 10, the coordinates prescribed time before the time when the switch 42 b is turned to the on state (for instance, the coordinates immediately before it is turned to the on state) may be fixed as the coordinates of the pointer 83 or the like. In this case, it is assumed that the remote controller 21 in FIG. 10 includes a memory that holds the calculated coordinates for a fixed period.

By such a configuration, it is possible to prevent the situation that the coordinates of the pointer 83 or the like is changed when the switch 42 b is turned to the on state.

[Operation Description of Remote Controller 21 in FIG. 10]

Next, with reference to a flowchart in FIG. 12, coordinate lock processing performed by the remote controller 21 in FIG. 10 will be described.

In step S61, the processing unit 101 detects the operation content and the operation target of the user operation on the basis of the detection results from the operation surface 42 a and the switch 42 b and the target user operation area from the area selection unit 44. Then, the processing unit 101 calculates the coordinates of the pointer 83 or the like corresponding to the position on the operation surface 42 a where the finger of the user or the like is in contact, on the basis of the detection result.

That is, for instance, when the pointer operation area A is supplied as the target user operation area from the area selection unit 44, the processing unit 101 calculates the coordinates of the pointer 83 on the basis of the operation content of the user operation included in the detection result.

In step S62, the processing unit 101 determines presence/absence of the pressure on the operation surface 42 a, that is, whether or not the switch 42 b is turned to the on state, on the basis of the detection results from the operation surface 42 a and the switch 42 b. When it is determined that the switch 42 b is not turned to the on state and is kept in the off state, the processing unit 101 advances the processing to step S63.

Also, the processing unit 101 may determine the presence/absence of the pressure on the operation surface 42 a, on the basis of one of the detection result of the operation surface 42 a and the detection result from the switch 42 b.

That is, for instance, the processing unit 101 determines the presence/absence of the pressure on the operation surface 42 a, on the basis of the detection result of the presence/absence of the pressure on the operation surface 42 a by the operation surface 42 a. The operation surface 42 a can detect the presence/absence of the pressure on the operation surface 42 a on the basis of the change in the electrostatic capacitance of the operation surface 42 a.

It can be said that it is equivalent to determine the presence/absence of the pressure on the operation surface 42 a on the basis of the change in the electrostatic capacitance of the operation surface 42 a by the processing unit 101.

Also, for instance, the processing unit 101 determines the presence/absence of the pressure on the operation surface 42 a, on the basis of the detection result from the switch 42 b indicating which of the on state and the off state the switch 42 b is in. It can be said that it is equivalent to determine the presence/absence of the pressure on the operation surface 42 a on the basis of whether or not the switch 42 b is in the on state by the processing unit 101.

In step S63, the processing unit 101 supplies the coordinates calculated in step S61 to the IR transmission unit 46. Then, the IR transmission unit 46 generates the IR signals including the coordinates from the processing unit 101, and advances the processing to step S66.

Also, in step S62, when it is determined that the switch 42 b is in the on state on the basis of the detection results from the operation surface 42 a and the switch 42 b, the processing unit 101 advances the processing to step S64.

In step S64, the processing unit 101 supplies the coordinates calculated in immediately preceding step S61 as the coordinates of the time when the switch 42 b is turned to the on state to the coordinate holding unit 102 to be held by overwrite.

In step S65, the processing unit 101 reads the coordinates held in the coordinate holding unit 102 from the coordinate holding unit 102, and supplies them to the IR transmission unit 46. Then, the IR transmission unit 46 generates the IR signals including the coordinates from the processing unit 101, and advances the processing to step S66.

In step S66, the IR transmission unit 46 controls the television receiver 22 by transmitting the generated IR signals to the television receiver 22 as the radio signals.

In step S67, the processing unit 101 determines whether or not the coordinate fixation time has elapsed since the switch 42 b is turned to the off state, on the basis of the timing result of the timing unit 101 a that times the elapsed time from the time when the switch 42 b is turned to the off state. In the processing unit 101, the timing unit 101 a is incorporated.

When it is determined that the coordinate fixation time has not elapsed since the switch 42 b is turned to the off state on the basis of the timing result of the timing unit 101 a, the processing unit 101 returns the processing to step S65, and performs the similar processing thereafter.

Also, when it is determined that the coordinate fixation time has elapsed since the switch 42 b is turned to the off state on the basis of the timing result of the timing unit 101 a, the processing unit 101 returns the processing to step S61, and repeats the similar processing thereafter.

As described above, according to the coordinate lock processing, the coordinates of the time when the switch 42 b is turned to the on state are included in the IR signals and transmitted, from the time when the switch 42 b is turned to the on state.

Further, even after the switch 42 b is turned to the off state, the coordinates of the time when the switch 42 b is turned to the on state are included in the IR signals and transmitted during the coordinate fixation time.

Therefore, the coordinates of the pointer 83 displayed on the display screen of the television receiver 22 are fixed for the fixed time from the time when the depressing operation by the user is performed.

Thus, for instance, since it is possible to prevent the situation that the pointer 83 on the display screen of the television receiver 22 is moved against the intention of the user, the operability of the user operation using the operation surface 42 a can be improved more.

In the second embodiment, the remote controller 21 in FIG. 10 calculates the coordinates of the pointer 83 on the basis of the detection result from the touch pad 42 or the like, however, the coordinates may be calculated and fixed on the side of the television receiver 22.

In this case, for instance, the remote controller 21 in FIG. 10 detects the operation content and the operation target of the user operation, on the basis of the detection result from the touch pad 42 and the target user operation area from the area selection unit 44. Also, the remote controller 21 in FIG. 10 generates (acquires) pressing information indicating the presence/absence of the pressure on the operation surface 42 a by determining the presence/absence of the pressure on the operation surface 42 a on the basis of the detection result from the touch pad 42.

Further, the remote controller 21 in FIG. 10 transmits the detected detection result and the generated pressing information to the television receiver 22. Then, the television receiver 22 receives the detection result and the pressing information from the remote controller 21 in FIG. 10, and performs the processing similar to the coordinate lock processing in FIG. 12 on the basis of the received detection result and pressing information.

That is, for instance, the television receiver 22 calculates the coordinates of the pointer 83 on the basis of the received detection result. Further, the television receiver 22 controls a built-in display so as to fix the coordinates of the pointer 83 for some time after it is determined that the switch 42 b is turned to the on state on the basis of the received pressing information. In this way, the television receiver 22 prevents the situation that the pointer 83 is moved against the intention of the user.

3. Modification

In the first embodiment, the remote controller 21 selects the target user operation area on the basis of the start position on the operation surface 42 a, for instance.

However, otherwise, for instance, the area selection unit 44 may select the target user operation area on the basis of the state of the content displayed on the display screen of the television receiver 22 as well in addition to the start position on the operation surface 42 a.

Also, in the remote controller 21, the state of the content is recognized on the basis of the user operation to the remote controller 21, for instance. Also, for instance, the state of the content may be recognized by the remote controller 21 by transmitting the state of the content appropriately from the television receiver 22 to the remote controller 21.

That is, for instance, in the case that the content that is being reproduced are displayed on the display screen of the television receiver 22, when the finger of the user or the like is brought into contact with the operation surface 42 a, the area selection unit 44 may select the target user operation area defined beforehand regardless of the start position on the operation surface 42 a.

Specifically, for instance, the area selection unit 44 selects the user operation area (for instance, the button area C) for which the content that is being reproduced are the operation content, as the target user operation area defined beforehand regardless of the start position on the operation surface 42 a.

For instance, in the case that the content that is being reproduced are not displayed on the display screen of the television receiver 22, when the finger of the user or the like is brought into contact with the operation surface 42 a, the area selection unit 44 selects the target user operation area on the basis of the start position on the operation surface 42 a.

The area selection unit 44 may also select the target user operation area using the start position on the operation surface 42 a, the required time until the tap operation, and the state of the content, other than using the start position on the operation surface 42 a and the state of the content.

Further, for instance, when the user performs the depressing operation when the pointer 83 is moved onto the content by the contact moving operation targeting the pointer operation area A, on the display screen of the television receiver 22, the content that is being reproduced are displayed.

In this case, for instance, the area selection unit 44 may select the user operation area (for instance, the button area C) for which the content of a reproduction target is the operation target as the target user operation area regardless of the start position on the operation surface 42 a or the like, in response to the depressing operation by the user.

Also, it is assumed that the content of the reproduction target is held in a server connected with the television receiver 22 through the Internet or the like, for instance.

Also, for instance, the area selection unit 44 may select the target user operation area on the basis of the state of the user as well in addition to the start position on the operation surface 42 a.

That is, for instance, when the user visually recognizes the operation surface 42 a, the area selection unit 44 selects the target user operation area on the basis of the start position on the operation surface 42 a.

This is because that, when the user performs the user operation in the state of visually recognizing the operation surface 42 a, a desired user operation area to be the target of the user operation can be accurately touched with the finger of the user or the like.

Also, for instance, when the user does not visually recognize the operation surface 42 a, the area selection unit 44 selects the target user operation area defined beforehand regardless of the start position on the operation surface 42 a.

Specifically, for instance, when the user does not visually recognize the operation surface 42 a, it is highly possible that the user is viewing the content displayed on the display screen of the television receiver 22. Therefore, for instance, the area selection unit 44 selects the target user operation area (for instance, the button area C) for which the content is the operation target.

The area selection unit 44 may also select the target user operation area using the start position on the operation surface 42 a, the required time until the tap operation, and the state of the users, other than using the start position on the operation surface 42 a and the state of the users.

Here, the state of the user is determined by the remote controller 21 on the basis of a captured image obtained from an imaging unit that images the user, for instance. The imaging unit can be configured to be provided in one of the remote controller 21 and the television receiver 22, for instance.

In the first embodiment, the remote controller 21 calculates the start position on the operation surface 42 a on the basis of the detection result from the touch pad 42, and selects the target user operation area on the basis of the calculated start position. Then, the remote controller 21 detects the user operation targeting the selected target user operation area.

However, otherwise, for instance, the television receiver 22 may be configured to detect the user operation to the operation surface 42 a of the remote controller 21.

In this case, the remote controller 21 transmits the calculated start position and the detection result from the touch pad 42 to the television receiver 22.

In contrast, the television receiver 22 receives the start position and the detection result from the remote controller 21, and selects the target user operation area on the basis of the received start position. Then, the television receiver 22 detects the user operation targeting the selected target user operation area on the basis of the detection result received from the remote controller 21 similarly, and performs the processing according to the detected user operation. That is, the television receiver 22 decides the operation corresponding to the target user operation area on the basis of the detection result received from the remote controller 21, and performs the decided operation (for instance, the operation of moving the pointer 83 or the like). It is similar in the second embodiment as well.

In addition, for instance, when a set-top box is connected to the television receiver 22, instead of the television receiver 22, the set-top box may receive the start position and the detection result from the remote controller 21 and detect the user operation.

Here, the set-top box is a device for converting received broadcast signals to signals that can be reproduced in the television receiver 22.

Also, in the first and second embodiments, the remote controller 21 including the operation surface 42 a provided on a part different from the display screen that displays the content has been described. However, the present technology is applicable even to a smartphone or the like including the operation surface 42 a that functions also as the display screen which displays the content or the like, for instance.
